Detailed Description
The following examples are intended to illustrate the present disclosure, but are not intended to limit the scope of the present disclosure.
Example 1
The present disclosure provides a detection method of an automatic braking system, which may be performed by a test terminal, which may be implemented by software and/or hardware. Optionally, the test terminal includes, but is not limited to, a computer, a server, and the like. In this embodiment, the test terminal is taken as an example for detailed description.
The present disclosure provides a method for detecting an automatic braking system, as shown in fig. 1, the method may include the steps of:
and S110, acquiring a light state signal of the prompting lamp in a terminal detection mode.
The disclosed embodiments provide terminals for detection including, but not limited to, desktop computers and mobile terminals. The application program of the terminal comprises a terminal detection mode for detecting the AEB installation condition, and the AEB after installation can be detected in real time through the terminal detection mode.
As shown in fig. 2, the AEB provided in the vehicle according to the embodiment of the present disclosure includes at least: the device comprises a control module, an acquisition module, a communication module and a vehicle-mounted positioning module.
The test terminal communicates with an AEB installed in a vehicle in a wireless communication and/or wired communication manner. The control module is respectively in communication connection with the acquisition module, the vehicle-mounted positioning module and the communication module. Meanwhile, the control module is in communication connection with a brake module of the vehicle so as to control the speed of the vehicle through the brake module. The acquisition module transmits the acquired parameter values to the control module, and then the acquired parameter values are uploaded by the control module through the communication module. The light state signal of the prompting lamp is collected by the collection module.
The wired communication includes: serial communication, parallel communication, local area network communication and/or internet communication;
the wireless communication includes: bluetooth communication, infrared communication, and mobile communication.
The prompting lamp is arranged outside the vehicle to which the device to be tested belongs and is used for reminding other road users of paying attention to the position of the vehicle or the driving direction of the vehicle. For example, the indicator lights include turn lights and/or dual flashing lights; the turn light is used for reminding other road users of paying attention to the fact that the vehicle changes the driving direction; the double flashing light is used for reminding other road users of paying attention to the position of the vehicle.
The light status signal is controlled by a driver, and comprises an opening signal and a closing signal. For example, when the vehicle is about to turn left, the driver turns on the left turn light through the left turn switch, and the light status signal is converted from the off signal to the on signal; when the vehicle runs straight, the left steering switch is automatically reset or manually reset by the driver, and meanwhile, the light state signal is converted from an opening signal to a closing signal.
And S120, responding to the light state signal as an opening signal, and if the automatic braking system of the vehicle is determined to be closed to perform braking control on the vehicle, acquiring an operation control parameter value and a braking parameter value.
The automatic braking system of the vehicle is turned off to perform braking control on the vehicle, which can be understood as that a control module of the automatic braking system of the vehicle turns off the control on a braking module of the vehicle. The brake module includes a master cylinder and brakes, and is capable of controlling the brakes by inputting pressure in the master cylinder to decelerate or park a traveling vehicle. The brake module can be controlled either automatically by the control module in the AEB or manually by the driver via the operating module. The brake parameter value is used to indicate a degree of braking of the vehicle, e.g. the brake parameter value comprises a pressure parameter value in a brake master cylinder.
The operating control parameter value is used to indicate the extent of driver influence on the brake parameter value-for example, the acquisition module of the AEB includes a travel sensor for measuring the extent to which the operating module is operated and generating the operating control parameter value.
The operation module is used for controlling a brake module of the vehicle by a driver and comprises a brake pedal and a manual brake. The control modes of the operation module comprise a mechanical mode and/or an electronic mode, such as an electric control brake pedal, a bus communication brake and an electric control manual brake.
Optionally, the obtaining operation control parameter values includes: and acquiring the operation control parameter value through an acquisition module in an automatic braking system of the vehicle. The acquisition module of the AEB includes a brake sensor for acquiring brake parameter values.
The operation module can control the running vehicle to decelerate or stay through a certain travel. And in the process of controlling the operation module by the driver, the stroke sensor continuously collects operation control parameter values and transmits the operation control parameter values to the control module. Meanwhile, the brake sensor also continuously collects brake parameter values and transmits the brake parameter values to the control module.
In the disclosed embodiment, the brake module can be controlled either automatically by the control module of the AEB or manually by the driver via the operating module.
The implementation of the present disclosure provides a way to safely control a vehicle, that is, after a light status signal of a vehicle warning light is an on signal, it indicates that a driver is in a normal driving state, and an AEB needs to release the control of the brake module.
And S130, responding to the condition that the operation control parameter value is larger than or equal to a preset operation control threshold value and the brake parameter value is larger than or equal to a preset brake threshold value, and generating normal detection information.
The operation control parameter value is greater than or equal to a preset operation control threshold value and the brake parameter value is greater than or equal to a preset brake threshold value, which can be understood as that the brake module can enable the vehicle to be in a deceleration state or a parking state under the control of the operation module. Therefore, it can be determined that the control module not only releases the control of the brake module, but also the driver can control the brake module through the operation module to make the vehicle in a deceleration state or a parking state, and the detection result is normal.
Optionally, S120a, in response to the light status signal being an on signal, if it is determined that the automatic braking system can perform braking control on the vehicle, generating detection abnormality information.
When the light state signal of the vehicle prompting lamp is the turn-on signal, the driver is in a normal driving state. The AEB can still control the brake module, namely the AEB can control the deceleration and the parking of the vehicle through the brake module, and the detection result is abnormal.
Optionally, S130a, in response to that the operation control parameter value is greater than or equal to a preset operation control threshold value and the brake parameter value is less than a preset brake threshold value, generating abnormal detection information;
or, in response to the operation control parameter value being smaller than a preset operation control threshold value and the brake parameter value being greater than or equal to a preset brake threshold value, generating detection abnormality information.
When the light state signal of the vehicle prompting lamp is an on signal, the driver is in a normal driving state, after the automatic braking system of the vehicle is turned off to brake the vehicle, the driver cannot normally brake the vehicle, and the detection result is abnormal.
The implementation of the present disclosure provides a detection mode for ensuring the safety of vehicle braking. In the terminal detection mode, after the prompting lamp is turned on, if the automatic braking system of the vehicle is determined to be turned off to perform braking control on the vehicle, whether the operation control parameter value and the braking parameter value of the vehicle meet the normal condition of the detection result is checked, and if the driver can normally control the deceleration or the residence of the vehicle through the operation module, the detection result is normal. Thereby providing a simple method for front-line service personnel to test the automatic braking system of the vehicle.

Optionally, S230a, in response to that the operation control parameter value is greater than or equal to a preset operation control threshold value and the brake parameter value is less than a preset brake threshold value, generating abnormal detection information;
or, in response to the operation control parameter value being smaller than a preset operation control threshold value and the brake parameter value being greater than or equal to a preset brake threshold value, generating detection abnormality information.
The embodiment of the disclosure uploads the detection data acquired by the AEB to the server, so that the detection data of a front-line service staff can be reserved through the server for tracing the installation process, finding problems and solving the problems. Meanwhile, a front-line service person detects the automatic braking system through the mobile terminal, so that the weight of the portable equipment is reduced, and the mobility is facilitated. The data transmission is carried out through the wireless communication module, so that the limitation of an application environment is avoided, and the application flexibility is improved.
Example 3
Since the embodiments of the present disclosure are further optimized based on the above embodiments, the explanations based on the same method components and the same name meanings are the same as those of the above embodiments, and are not repeated herein.
Before the light state signal of the prompting lamp is obtained, the method further comprises the following steps:
s310, acquiring first position information acquired by a vehicle-mounted positioning module in an automatic braking system of the vehicle.
As shown in fig. 2, the AEB provided in the vehicle according to the embodiment of the present disclosure at least includes a control module and a vehicle-mounted positioning module, where the control module obtains and uploads first position information of the vehicle through the vehicle-mounted positioning module, so that the terminal for testing obtains the position information.
And S320, acquiring second position information through the terminal positioning module.
The terminal comprises a terminal positioning module, and second position information of the terminal is acquired through the terminal positioning module.
The first location information and the second location information may be from a satellite positioning system, such as, for example, the beidou system or the global positioning system; but also from mobile communication locations such as triangulation of mobile base stations. The first position information and the second position information may also be represented by different types of coordinate systems, such as an astronomical coordinate system, a geodetic coordinate system and/or a geocentric coordinate system. The disclosed embodiments are not limiting.
S330, calculating a distance value between the first position information and the second position information.
When the distance value is calculated, the first position information and the second position information need to be unified into a coordinate system of the same type, so that the distance value can be accurately calculated.
S340, if the distance value is smaller than or equal to a preset distance threshold value, triggering the execution of the operation of obtaining the light state signal of the prompt lamp.
When the distance value is smaller than or equal to the preset distance threshold value, the fact that the vehicle and the terminal used for testing are located at the same position can be understood, and the vehicle-mounted positioning module works normally. The terminal can be used to test the vehicle. If the terminal used for testing is not in the same position as the vehicle, i.e. the distance value is greater than the preset distance threshold, the terminal cannot be used for testing the vehicle, thereby ensuring the authenticity of the test.
The vehicle-mounted positioning module is an important unit for providing safety guarantee for the vehicle by the AEB. The vehicle-mounted positioning module can work normally and is a precondition for normal work of the AEB.

And the terminal detection mode is matched with the intelligent detection mode. It can be understood that the terminal detection mode and the intelligent detection mode can cooperate to complete the task of detecting the AEB. Therefore, once the control module of the AEB enters the intelligent detection mode, the terminal also enters the corresponding terminal detection mode to start detection.
